<pre>I have found this behaiviour because of error in my code when some time
is_format_supported called with uninitialized value and had value >
PIPE_FORMAT_COUNT.
With check like:
-----
for(int i=0; i<PIPE_FORMAT_COUNT; i++) {
pscreen->is_format_supported(pscreen, i, PIPE_TEXTURE_2D, 0,
PIPE_BIND_SAMPLER_VIEW);
}
-----
Such code has possible issues with: 73, 78, 79, 80, 81, 86 (holes in enum
pipe_format).</pre>
